	Abstract:	In high-pressure die casting processes, proper control of die temperature is essential for producing superior quality components and yielding high production rates. Very often it is impractical to control die temperature to a specific point during solidification stages. In this paper, a computerised Intelligent Real-Time Monitoring and Control System (IRMCS) is developed for die casting processes involving cooling of a die with multiple channels. A local temperature controller is designed to confine temperature fluctuations of a die within a desirable range. The performance of the system is evaluated through a laboratory die casting process simulator in terms of measurement accuracy, time delay and local heat removal rate. The experimental results indicate that the developed control system is capable of adjusting the desirable supply of cooling water into multiple cooling lines. Hence, the ideal thermal pattern of the die becomes achievable.
